This is another post providing a generic response to emails I get from students.
Any Extra credit earned is added to the final overall grade, up to a total of 10%. Extra credit is a component of the final grade. For every component of the course, Angel returns a score out of 100%. Thus, to add three points of extra credit (for example), I need to tell Angel a score of 30% and that then ensures that 3 points (30/100) gets added to the final score for extra credit. This shows up on Angel as Extra credit Category Total = 30% .
Thus, 3 points of extra credit = 30%, 5 points = 50% and 10 points = 100% of extra credit.
